An air-pressure sprayer. The air-pressure sprayer includes a container, a cover unit, an air-pump unit, a spray mouthpiece unit, and a water-stop valve wherein the cover unit, screw jointed to said container, has a press body disposed at one side thereof which can control the movement of the water-stop valve located in parallel position at the other side thereof. The air-pump unit has a valve rod with a head knob disposed at the top and an air-relief valve attached at the bottom thereof. The valve rod and the air-relief valve are led through a sleeve cylinder and joined to the cover unit at the upper section. The spray mouthpiece unit, attached to one side of said cover unit via a sleeve body and a pivot body, can be moved upwards or downwards to point at different directions for use.

1. An air-pressure sprayer structure, comprising:a container, a cover unit, an air-pump unit, a spray mouthpiece unit, and a water-stop valve wherein said container is provided with a water-inlet opening and external threads at an upper section thereof;said cover unit, joined to said container via s
1. An air-pressure sprayer structure, comprising:a container, a cover unit, an air-pump unit, a spray mouthpiece unit, and a water-stop valve wherein said container is provided with a water-inlet opening and external threads at an upper section thereof;said cover unit, joined to said container via said external threads thereof, has a press body disposed at an upstream thereof which can control movement of said water-stop valve disposed in a sleeve pipe;said air-pump unit, accommodated within said container, comprises a valve rod having a head knob extending out of said cover unit at a top thereof, and an air- relief valve disposed at an end thereof wherein said engaged valve rod and air-relief valve are led and joined to a sleeve cylinder;said spray mouthpiece unit, attached to said cover unit at a downstream side thereof, can be moved upwards or downwards to point at different directions for use;whereby, said press body having a slide block can be located for constant discharge of water out of said spray mouthpiece without interruption; andthe force applied onto said press body being in parallel with a longitudinal axis of said water-stop valve thereof, allowing a balance of forces in operation and effectively preventing the distortion of said water-stop valve and thus a leak of both air and water from said container. 2. The air-pressure sprayer structure as claimed in claim 1, wherein said cover unit comprises an engaging body, a press body, a spring, and a cover body; said engaging body is joined to said cover body via a mounting means which is provided with a fixing hole to be engaged with a fixing block of an abutting of said cover body thereof; said press body is located between said engaging body and said cover body, having said spring sandwiched there-between said press body and said cover body thereof; a press section is disposed at one side of said press body wherein said press section has a slide block with locating posts disposed thereon to pushed back and forth for location. 3. The air-pressure sprayer structure as claimed in claim 1, wherein said air-pump unit comprises a valve rod, an air-relief valve, a sleeve cylinder, a locating seat, an air-intake pipe, and a valve guard member; said valve rod having a head knob extending out of said cover unit at the top thereof, and a rod body extending downwards to be engaged with said air-relief valve at the end thereof; said air-relief valve, having a spring and a ball disposed therein, and said rod body thereof is led and placed within said sleeve cylinder wherein said sleeve cylinder is provided with a sleeve part at the bottom to which said valve guard member is attached; said locating seat having one large and one small pivot slots disposed thereon is applied to joint both said air-intake pipe and said sleeve cylinder at the lower section thereof. 4. The air-pressure sprayer structure as claimed in claim 1, wherein said spray mouthpiece unit comprises a sleeve body, a pivot body, a shade body, and a spray nozzle; one end of said sleeve body is provided with a coupling hole having a pair of fixing holes disposed at both sides thereon, and one lateral side of said sleeve body is a pivoting column with a first pivot hole disposed therein corresponding to a second pivot hole disposed at one lateral side of said pivot body so as to pivot joint both said sleeve body and pivot body via an anti-loose bolt and nut; said pivot body having external thread disposed at one end so as to be engaged with said shade body and said spray nozzle for use.
